To 'aZZ whom it may concern.-

Be it known that I, THEODORE L. VALE- RIUs, a citizen of the United States, residing at Fort Atkinson, in the county of Jefferson 5 and State of Wisconsin, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following is a specification.

The object of this invention is the producto tion of an improved bottle-filling machine.

In the accompanying drawings, Figure 1 is a side elevation of this bottle-filling machine. Fig. 2 is a vertical section on dotted line 2 2 of Fig. 3. Fig. 3 is a front elevation i 5 of the machine. Fig. 4 is a horizontal section on dotted line 4 L of Fig. 3. Fig. 5 is a similar section on dotted line 5 5 of Fig. 3. Fig. 6 is a detail View of the bottle-elevating mechanism and discharge-spout, showing the botzb tle in dotted lines. Fig. 7 is a similar view of said mechanism, showing the valve in the discharge-spout open ed to admit liquid to the interior of the bottle. Fig. 8 is a vertical central section through said discharge-spout.

5 Fig. 9 is a vertical central section showing the vertical elevator-plunger and its supporting-bearings.

Like letters of reference indicate corresponding parts throughout the several views.

In the production of this bottle-filler I provide a table A, having the top A with the bottle-guides A thereon, the supporting-legs A and the horizontal braces A between said legs.

B is a liquid-reservoir mounted above the tabletop A, and B is a filler extension thereof forming the forward part of said main reservoirBand communicatingtherewith by means of the pipe B This pipe 13 is automatically 4o controlled by the closure 13 and the float B", so that a certain predetermined quantity of liquid in the filler-reservoir B is constantly maintained.

C is a rod screw-threaded at its lower end 5 and, extending upward through an opening in the table-top A, supports the liquid-reservoir over said table. A bevel-gear C with a long integral hub 0 internally screw-threaded to correspond with the threads upon the rod 0, provides means for adjusting the height of said reservoir B. A shaft C mounted in the bearings C secured to the under side of the table-top,supports the bevel-gear C ,meshing with the bevel-gear C, the forward end of the shaft 0 being squared at (3 for the attachment of a suitable crank. (Not shown.) Fixed rods C extend upward from the tabletop A beside the liquid-reservoir B and are adapted to be clamped thereto by means of the brackets C and the thumb screws C thereon. Side rails C extend forward from said fixed rods at each side of the table-top and at their forward ends are secured to said table. Their purpose is to prevent bottles from falling from the table.

, Treadle-levers D are pivotally mounted upon the rod D, extending between the two rear legs A of the table A. These levers extend forward and have between their free ends the treadle D Two extension coilsprings D connected with said treadle-levers and adapted to hold the same elevated, are attached at their upper ends to the hooks D secured to the under side of the table-top A and at their lower ends to the rod D extending between said levers D.

Four elevator-disks E project above the table-top A between the guides A thereon. These disks are fixed at the upper ends of rods E, which latter extend downward through their bearing sleeves E and through openings E in the cross-bar A, between the forward legs A Coil-springs E surround said rods and collars E limit the upward movement of said coil-springs. A cross bar E perforated at suitable intervals to permit the passage of said rods, extends beneath said coil-springs E and the collars E are secured to said rods directly beneath said cross-bar. Links E are pivotally secured at their lower ends to the ends of the cross-bar E and at their upper ends to the levers E pivotally mounted in the bracket E secured to the table A at either side thereof. The opposite end of each of the lovers E is connected by 5 means of the link E with one of the treadlelevers D. The lower ends of the links E are provided with the elongated openings E adapted to receive the rod D extending between the two treadle-levers D.

Several discharge-spouts F are located in the bottom of the filler-reservoir B, com municating with the interior thereof, one of said discharge-spouts being directly over each of the elevator-disks E. Each discharge spout is closed bya conical. plug F and is provided with the rubber packing-ring F at its lower end. This packing-ring is adapted to form a tight joint with the mouth of the bottle when the same is raised by the elevator-diskE into contact with said rings. These plugs are secured at the lower ends of the valve-stems F ,extending upward through and above the dischargespouts F, and through suitable openings F in the fixed supporting-bar Fiwithin the fillerreservoir B. These valve-stems F are made tubular, so that air within the bottles being filled may escape through said valve-stems as it is displaced by the inflowing liquid. Above said supporting-bar F the stems F are surrounded by the coil-springs F, and above said springs are provided with the collars F Extending across said collars and perforated at suitable intervals to receive the valvestems F is a cross-bar F having the openings F at its outer ends to receive the vertical rods F These rods are provided with the adjustable stops F at their upper ends, and extending downward have a pivotal-connection with the treadle-lever D on each side of the machine.

Two vertical feeder-levers G are pivotally mounted in the bracket G, secured to the forward leg of the table A. These feeder-levers are each provided near their lower ends with the cam-groove G somewhat of the form of the figure 4. Near the upper angle of these cam-grooves are provided the pivoted switches G A fixed stud Gr extends outward from each of the treadle-levers D and engages said cam-groove. By reason of the switches G the studs G are directed downward into the inclined portion of the cam-groove, returning upward in the stem portion thereof, opening the switches near the upper part of their movement. At the upper end the feeder-levers G are connected by the pivoted bail G in the side arms of which are provided the adj Listing-sleeves G internally threaded with right and left screw-threads to permit of an adjustment of the transverse bar G of said bail for different sizes of bottles. This transverse bar G is provided with a rubber covering G in order that it shall not break the bottles to be filled.

In operation empty bottles are placed upon the table-top A, near the forward end thereof and Within the guides A The liquid to be bottled is placed in the reservoir B, the float B permitting a certain quantity of said liquid to run through the pipe B into the filler-reservoir B. The foot of the operator is placed upon the treadle D and the treadlelevers D depressed. The first movement of the mechanism is the forward movement of the feeder-levers G, pushing the empty botamt tles into line directly over the elevator-disks E and then retreating slightly to withdraw the transverse bar G from contact with the bottles. This movement of the feeder-levers G occurs when the studs Gt descend through the angular portion of the cam-grooves G of said feeder-levers G. WVhen the studs G have reached the lower part of said angular portion of the cam-grooves G and enter the stem portion of said grooves, the rod D has traveled the length of the elongated opening E in the link E and said link is then drawn downward, tilting the lever E upon its pivot and raising the elevator-disks E with the bottles resting upon them. This movement lifts the bottles so that their necks are placed in engagement with the elastic collar F of the discharge spouts F, holding said bottles tightly in contact with said packing and making a tight joint between the bottles and the discharge-spouts. A continued downward movement of the treadle D causes the rods F to be drawn downward through their openings F in the ends of the cross-bar F until the adjustable stops F at the upper ends of said rods F engage the upper side of said crossbar. As soon as this occurs a continued depression of said treadle-levers D depresses the cross-bar F compresses the springs F, coiled about the valve-stems F and moves the closure-plugs F from their seats in the spouts, thus opening said spouts and permitting the liquid within the fillerreservoir to run into the bottles to be filled. As soon as the bottles are filled with liquid the foot of the operator is removed from the treadle D the treadle-levers D are raised by the action of the coil-springs E the closureplugs F seat themselves within the dischargespouts F, and the supply of liquid is cut off. A continued upward movement of the treadle D permits the elevator-disks E to recede downward, and the filled bottle rests upon the guides A upon the table-top A. While these bottles were being filled, four empty bottles were placed by the operator within the bail G and a second depression of the treadle D brings said empty bottles forward over the elevator-disks E, to be raised and filled as were the preceding ones, pushing the filled bottles backward in the guides A As empty bottles are pushed forward by the feederbail G5 to be filled the filled bottles are slid along the guides A onto the table-top A. Here they are capped by an assistant and removed from said table.

To adjust the height of the reservoir B to different sizes of bottles, the shaft C and the bevel-gears O and O are rotated. The thread connection between the bevel-gear O and its sleeve 0 with the rod 0 causes said reservoir to be raised or lowered as said shaft is turned. The set-screw C in the bracket O for engag ing the rods 0" at the sides of the reservoir, rising from the table-top to the reservoir 13, must of course be loosened before a change in the adjustment of the reservoir and tightened again after such adjustment has taken place.

The conical form of the closure-plugs F causes the liquid to be injected into the bottles in a thin sheet directedagainst the inner sides thereof, thus preventing all foaming of the liquid caused by the filling process.
